Roger Federer vs. Guido Pella: Score and Reaction from 2016 Wimbledon

Roger Federer was made to work hard by Guido Pella in his opening match of Wimbledon 2016 but eventually booked his place in the second round with a 7-6(5), 7-6(3), 6-3 win over the Argentinian.

The world No. 3 and seven-time former champion in SW19 could not claim a single break point in the opening two sets but took them both on a tiebreak.

He then turned on the style to claim the third set 6-3 and beat the left-hander in just over two hours.

Pella impressed with excellent movement and remarkable resilience, and he went toe to toe with arguably the greatest grass player of all time despite never having prevailed in a match on the surface, per ESPN's Trey Wingo:

Federer did not immediately look at his brilliant best, and Pella moved well on Centre Court, with the pair exchanging the opening six games.

The Swiss then forced two break points at 4-3 ahead but saw them both saved, a feature that would become a theme of the opening two sets.

Having earned a tiebreak, Pella must have fancied his chances of bagging the opener, but Federer went up a gear to win the breaker 7-5.

He then put Pella through the mill in the opening game of the second set, forcing four break points, none of which he could take.

The Argentinian got to everything, picking up what looked a certain winning volley from Federer and eventually moving into a 1-0 lead.

The Swiss legend responded with a rapid-fire hold, and the set settled into a pattern of Pella working hard to retain his serve as Federer cruised.

The frustration was palpable, though, from Federer, who failed to take any of his six break-point opportunities while conceding none, per ESPN's Brad Gilbert:

The only sniff of a chance for Pella came at 6-5 as he took a 0-30 lead on Federer's serve, but he responded with four first serves to force another tiebreak.

And having been just two points from taking the set, Pella was soon 4-0 down in the breaker, with Federer upping his game once again to go two sets clear, per Live Tennis:

Pella's head did not drop, but he continued to have to work very hard to hold. He finally cracked at 4-3 down in the third as Federer dispatched two thumping forehands down the line to claim his first break of the match.

He served out the match in efficient fashion, finishing with an ace, and will now take on Britain's Marcus Willis in the next round.
